To learn more about ASME B31.5 and the 5 year warranty, please contact Colmac Coil at. Systems for Liquid Hydrocarbons, B31.5 Refrigeration Piping and Heat Transfer Components, B31.8 Gas Transmission and. At Colmac the top priority is the safety of people and products! Colmac’s commitments to ASME quality systems and extensive in-house welder training allows them to warrant all of the pressure bearing elements in stainless steel tube ammonia evaporators (tubes, headers, connections, weld joints) to be free of defects in materials and workmanship for a period of 5 years. Full compliance with ASME B31.5 for evaporator construction insures that the ammonia refrigeration system is constructed with the same consistent quality standards throughout.Ĭolmac has also recently introduced its new 5 year warranty for coil cores. When a local building Code (which is the law -jurisdiction) requires the use of one of the B31 Codes, only then does it have 'the force of law.

ASME B31 Pressure Piping Codes are 'voluntary consensus Codes'. IIAR-2 requires that ammonia piping systems be built and installed according to the requirements of ASME B31.5. ASME B31.1 & ASME B31.3, both Codes spell out their intended scopes and their rules are 'valid' for the intended scope. Colmac Coil utilizes the quality systems defined by ASME Sections XIII and IX of the Pressure Vessel Code for the design and manufacture of its ammonia heat exchangers. The design, materials, fabrication, examination, and testing of every Colmac Coil ammonia evaporator coil complies fully with the requirements of the ASME Code for Pressure Piping B31.5 “Refrigeration Piping and Heat Transfer Components”. Refrigeration Piping and Heat Transfer Components ASME Code for Pressure Piping, B31 A N A M E R I C A N N A T I O N A L S T A N D A R D ASME B31.5-2016. Colmac’s full adherence to ASME B31.5 standards demonstrates a long standing commitment to producing quality products for the industrial refrigeration market.
